On the upcoming episode of “Superman Returns,” Chu Sarang visits Seo Eon and Seo Jun‘s house during her temporary stay in Korea.

When they meet, it seems like they haven’t actually been apart for all this time and act like siblings. Seo Jun has a storybook ready in his hand before Chu Sarang comes and when she arrives, Seo Jun follows her around exclaiming, “This, this!”

Seo Eon, on the other hand, has a great time playing on the seesaw with Chu Sarang and does not leave her side.

Although she knows how to have fun with the twins, she does not mess around when it comes to discipline. The cute toddler definitely plays the older sister role when Seo Eon and Seo Jun do not listen to their father’s words, and says, “No!” to the twins. Furthermore, she shows that she’s mature by figuring out how the twins want to play, and does her best to make the them happy.

To find out more of what happens during her visit to the twins’ house, watch the next episode of “Superman Returns” airing on August 30 at 4:50 p.m. KST.
